(1) the unit of measurement depends on parameter P2
(2) appropriately set the parameters relative to the regulators after modification of parameter P2
effect caused by the activation of the multipurpose input
0 = no effect
1 = SYNCHRONISATION OF DEFROSTING - on expiry of time d5 defrosting will be activated
2 = ACTIVATION OF THE ENERGY SAVING FUNCTION - the Energy Saving function will be activated (until the input is deactivated), on condition that the Overcooling function
is not in progress; see also r4
3 = ACTIVATION OF THE MUTIPURPOSE INPUT ALARM - when time i7 has expired, the display will show “
iA
” flashing and the buzzer will be activated (up to when the input
is deactivated)
4 = ACTIVATION OF THE PRESSURE SWITCH ALARM - the compressor will be off, if u1 and/or u11 = 6 the condenser fan will be on, the display will show the flashing “
iA
”
code and the buzzer will be activated (until the input is deactivated): when the input has been activated the number of times established by parameter i8 the regulators
will be switched off, if u1 and/or u11 = 6 the condenser fan will be switched on, the display will show the flashing “
iSd
” code and the buzzer will be activated (until
the input is deactivated and the instrument is switched off and back on again or the power supply is cut-off); see also i7 and i9
5 = AUXILIARY OUTPUT SWITCH-ON - the auxiliary output will be switched-on (only if u1 and/or u11 = 2, until the input is deactivated)
6 = INSTRUMENT SWITCH-OFF - the instrument will be switched off (until the input is deactivated)
type of multipurpose input contact
0 = normally open (active input with closed contact)
1 = normally closed (input open with contact open)
if i5 = 3, multipurpose input alarm signal delay (“
iA
” code)
if i5 = 4, compressor switch-on delay from the activation of the multipurpose input (21)
number of multipurpose input alarms (“
iA
” code) such to cause the pressure switch alarm (“
iSd
” code) (only if i5 = 4)
0 = no alarm
time that must pass in absence of multipurpose input alarms (“
iA
” code) so that the alarms contactor is reset (only if i5 = 4)
time that must pass without activation of the door micro switch input (after the cabinet temperature has reached the work set-point) so that the Energy Saving function is
activated automatically (it affects the evaporator fan only if F0 = 1 or 2)
0 = the function will never be activated automatically
minimum duration of door micro switch activation such to cause the exclusion of the consequent evaporator temperature value from those used for the calculation of the
relative average (for the activation of defrosting; only if d8 = 3); see also d17
minimum total duration of door micro switch activation such to cause the exclusion of the consequent evaporator temperature value from those used for the calculation
of the relative average (for the activation of defrosting; only if d8 = 3); see also d17
number of door micro switch input activations such to cause the activation of defrosting
0 = defrosting will never be activated due to the effect of door micro switch input activation
minimum duration of door micro switch input activations such to cause the activation of defrosting
0 = defrosting will never be activated due to the effect of door micro switch input activation
DIGITAL OUTPUTS
utility managed by the fourth output (22)
0 = CABINET LIGHT - in this case the key, parameters i0 and u2 will have meaning
1 = DEMISTING HEATERS - in this case the key and parameter u6 will have meaning
2 = AUXILIARY OUTPUT - in this case the key, parameters i5 and u2 will have meaning
3 = ALARM OUTPUT - in this case, parameter u4 will have meaning
4 = DOOR HEATERS - in this case, parameter u5 will have meaning
5 = EVAPORATOR VALVE - in this case, parameters u7 and u8 will have meaning
6 = CONDENSER FAN - in this case, parameters P4, F11 and F12 will have meaning
enabling of cabinet light or auxiliary output switch-on/off in manual mode when the instrument is off (only if u1 and/or u11 = 0 or 2) (23)
1 = YES
enabling deactivation of the alarm output with silencing of the buzzer (only if u1 and/or u11 = 3)
1 = YES
cabinet temperature below which the door heaters are switched-on (“u5 - 2.0
°
C/4
°
F, only if u1 and/or u11 = 4) (6)
duration of demisting heaters switch-on (only if u1 and/or u11 = 1)
cabinet temperature below which the evaporator valve is disabled (relative to the work set-point, i.e. “work set-point + u7”) (only if u1 and/or u11 = 5) (6)
type of evaporator valve contact (only if u1 and/or u11 = 5)
0 = normally open (active valve with closed contact)
1 = normally closed (active valve with open contact)
enabling of the buzzer
1 = YES
utility managed by the fifth output (22)
